What is the introduction of the metal nameplate to the material's performance requirements?
Metal nameplates are increasingly used in various fields in modern society, mainly widely used in electronic products, household appliances, machinery and civil products and other fields.So popular, mainly is the metal sign material performance requirements, need in the strength, hardness, plasticity, fatigue strength, impact toughness, etc.
I. strength:
Resistance to plastic deformation or fracture under load.
1. Symbol: yield strength s -- the minimum stress of the material at yield.The units are Mpa.
2. Tensile strength b -- the maximum stress a material is subjected to before breaking.The units are Mpa.
3. Application conditions and scope: the main basis for designing mechanical parts and material selection.
Ii. Hardness:
The ability of a surface of a metal plate to resist the deformation of another object within a local volume.
1. Symbol: brinell hardness HB;Rockwell hardness HR.
2. Application conditions and scope: brinell hardness is mainly used for measuring gray cast iron, non-ferrous metal plate, annealed, normalized and tempered steel materials.HBS is suitable for materials with a hardness value less than 450, and HBW is suitable for materials with a hardness value less than 650.
The rockwell hardness tester can measure both soft and hard metal materials.HRA is mainly used for measuring cemented carbide and surface hardened steel.HRB is mainly used for measuring mild steel, annealed steel, copper alloy, etc.HRC is mainly used to measure general hardened steel.
Iii. Plasticity
The ability of a metal plate material to produce plastic deformation under load without fracture.
1. Symbol: elongation after break -- the relative elongation of the standard distance after the specimen is broken.
2, reduction of area bits - after tensile sample, sample cross-sectional area of the relative reduction.
3. Application conditions and scope: the main basis for material selection during pressure processing.
Iv. Fatigue strength
Maximum stress of metal plate material without fracture under repeated alternating loads.
1. Symbol: fatigue strength -1
2, application conditions and scope: ferrous metal cycle cycle times 10 to the seventh power, non-ferrous metal plate and some high strength steel cycle times 10 to the eighth power.
V. impact toughness:
The ability of a metal nameplate material to withstand impact loads without damage.
1. Symbol: impact absorption work Ak;Impact toughness ak.
2. Application conditions and scope: impact toughness value is generally only used as a reference for material selection, not as a basis for calculation.The multiple impact resistance of materials mainly depends on the plasticity.The impact energy depends mainly on the strength.
In summary, the production of metal signs mainly based on copper, iron, aluminum, zinc alloy, titanium, stainless steel and other raw materials, through stamping, die-casting, etching, printing, enamel, imitation enamel, paint, drop plastic, electroplating and other processes.Its metal alloy nameplate on the material's performance requirements, is described above these specific content.
